Project description:As human blastocyst-derived extravillous trophoblasts (EVTs) invade the early decidua, they are positioned to interact with immune cells and resident decidual cells, and remodel spiral arteries into high capacity vessels that increase blood flow to the developing fetal-placental unit. Shallow EVT invasion elicits incomplete vascular transformation and reduces uteroplacental blood flow that presages adverse pregnancy outcomes. Excess macrophages in the decidua induce EVT apoptosis via tumor necrosis factor-alpha (TNF-?) secretion. Our previous observation that pro-inflammatory cytokines enhance neutrophil and macrophage activator granulocyte-macrophage colony-stimulating factor (GM-CSF) expression in first trimester decidual cells is now extended to include: (1) the specific macrophage activator M-CSF; (2) macrophage activation and subsequent enhancement of EVT apoptosis by both GM-CSF and M-CSF.Quantitative reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay assessed M-CSF expression in first trimester decidual cells incubated with interleukin-1 beta (IL-1?) or TNF-?. Peripheral monocyte-derived macrophages pre-incubated with conditioned media from decidual cell cultures were co-cultured with a first trimester EVT cell line, HTR-8/SVneo cells. Macrophage activation was examined and EVT apoptosis evaluated by DNA fragmentation, caspase activation and cell membrane asymmetry.IL-1? or TNF-? significantly enhanced M-CSF expression in first trimester decidual cells. The conditioned media from these cultures activates macrophages, which promote caspase 3/7-dependent EVT apoptosis with antibodies against GM-CSF or M-CSF blocking this effect.Pro-inflammatory cytokines increases synthesis of M-CSF in first trimester decidual cells. Both GM-CSF and M-CSF activate macrophages, which initiate caspase-dependent EVT apoptosis.

Project description:Zika virus (ZIKV) infection at the maternal-placental interface is associated with adverse pregnancy outcomes including fetal demise and pregnancy loss. To determine how infection impacts placental trophoblasts, we utilized rhesus macaque trophoblast stem cells (TSC) that can be differentiated into early gestation syncytiotrophoblasts (ST) and extravillous trophoblasts (EVT). TSCs and STs, but not EVTs, were highly permissive to productive infection with ZIKV strain DAK AR 41524. The impact of ZIKV on the cellular transcriptome showed that infection of TSCs and STs increased expression of immune related genes, including those involved in type I and type III interferon responses. ZIKV exposure altered extracellular vesicle (EV) protein, mRNA, and miRNA cargo, regardless of productive infection. These findings suggest that early gestation macaque TSCs and STs are permissive to ZIKV infection, and that EV analysis may provide a foundation for identifying non-invasive biomarkers of placental infection in a highly translational model.

Project description:Seven patient paired primary human HLA-G+ extravillous trophoblasts (EVT) and Villous trophoblasts (VT) obtained from 1st trimester (7-9 weeks) villous tissue were obtained. RNA was isolated directly after isolation and purification using FACS sort for CD45-HLA-G+ (EVT) and CD45-HLA-G-EGFR1+ (VT) fractions. Expression profiles were compared to two samples of the choriocarcinoma cell line JEG-3 and four samples of decidual stromal cells (DSC) at passage 2 after cell culture.

Project description:Purpose: During early placentation, extravillous trophoblast (EVT) cell invasion into maternal decidua plays a crucial role in establishment of the successful pregnancy. However, little is known about the characteristic features of EVT-associated ncRNAs. The purpose of this study is to elucidate gene expression profile for both coding and non-coding genes (i.e., mRNAs, lncRNAs, and miRNAs) expressed in EVT cells isolated from the first-trimester human placenta by RNA sequencing analysis. Methods: Human first trimester placental tissues (at gestational week 7, n=3) were obtained after legal abortions. EVT cells growing from explanted human chorionic villi were isolated. Minced chorionic villous tips were defined as first-trimester chorionic villous trophoblast (CVT) cells. Using total RNAs of these samples, mRNA/lncRNA-sequencing analysis was carried out on an Illumina MiSeq (San Diego, California, USA) using MiSeq v2 Reagent Kit 300cycle (cat. no. MS-102-2002; Illumina) and MiSeq v2 Reagent Kit 50cycle (cat. no. MS-102-2001; Illumina), respectively. The paired-end reads of 151 bp length for mRNA/lncRNA-sequencing and single reads of 26 bp length for miRNA-sequencing were obtained as fastq files which were imported into CLC genomics workbench (version 8.0.1; Qiagen, Venlo, Netherlands). Clean reads were aligned to the human genome sequence retrieved from the Ensembl database (Assembly GRCh38.p13, database version 82.38 and 101.38) and microRNA database miRbase (release 21), using CLC Genomics Workbench Map Reads to Reference tool. Normalization of gene expression data was performed by the TMM method of edgeR package. Statistically differentially expressed transcripts were conducted using edgeR. Genes that had a false discovery rate (FDR)-corrected p-value (q-value) of < 0.05 and an absolute log2 fold change (log FC) ≥ 1 were judged to be significantly differentially expressed (i.e., differentially expressed genes, DEGs). Results: Five thousand ninty-two mRNAs , 422 lncRNAs and 400 miRNAs were found to be differentially expressed. One hundred differentially expressed genes (i.e., 10 mRNAs, 7 lncRNAs, and 83 miRNAs) that are located in the chromosome 14q32.2 region containing the eutherian-specific imprinted DLK1-DIO3 domain were significantly down-regulated in EVT cells. In terms of imprinted genes (http://www.geneimprint.com/site/genes-by-species), 68 genes were found to be differentially expressed; 71% of these genes were down-regulated in EVT cells. lncRNA H19 was a DEG (q = 1.29.E-09, log FC = 2.98) and the most highly expressed lncRNA (70.47%) in EVT cells. Conclusions: The present research should be valuable for a resource for future ncRNA research in EVT cells.

Project description:This study aims to compare in vivo human trophoblast differentiation into EVTs to different in vitro trophoblast organoids using single-cell and single-nuclei RNA sequencing. The study includes two type of systems: human primary trophoblast organoids (PTO) and trophoblast stem cells (TSCs). Trophoblast stem cell (TSC) lines BTS5 and BTS11 derived by Okae and colleagues were grown as described previously (Okae et al. 2018) and together with EVT media. Primary trophoblast organoids (PTO) were grown and differentiated into EVT as previously described by Turco & Sheridan (Turco et al 2018; Sheridan et al 2020). This study shows that the main regulatory programs mediating EVT invasion in vivo are preserved in in vitro models of EVT differentiation from primary trophoblast organoids and trophoblast stem cells.

Project description:Invading human leukocyte antigen-G+ (HLA-G+) extravillous trophoblasts (EVT) are rare cells that are believed to play a key role in the prevention of a maternal immune attack on foreign fetal tissues. Here highly purified HLA-G+ EVT and HLA-G- villous trophoblasts (VT) were isolated. Culture on fibronectin that EVT encounter on invading the uterus increased HLA-G, EGF-Receptor-2, and LIF-Receptor expression on EVT, presumably representing a further differentiation state. Microarray and functional gene set enrichment analysis revealed a striking immune-activating potential for EVT that was absent in VT. Cocultures of HLA-G+ EVT with sample matched decidual natural killer cells (dNK), macrophages, and CD4+ and CD8+ T cells were established. Interaction of EVT with CD4+ T cells resulted in increased numbers of CD4+CD25(HI)FOXP3+CD45RA+ resting regulatory T cells (Treg) and increased the expression level of the Treg-specific transcription factor FOXP3 in these cells. However, EVT did not enhance cytokine secretion in dNK, whereas stimulation of dNK with mitogens or classical natural killer targets confirmed the distinct cytokine secretion profiles of dNK and peripheral blood NK cells (pNK). EVT are specialized cells involved in maternal-fetal tolerance, the properties of which are not imitated by HLA-G-expressing surrogate cell lines.

Project description:During early human pregnancy, extravillous trophoblasts (EVT) play a central role in placental anchorage and blood vessel remodeling. Despite the essential roles in pregnancy, key factors and mechanisms underlying EVT differentiation remain largely unknown. Here, we defined key transcription factors (TFs) by monitoring the dynamics of transcriptome and enhancer usage during EVT differentiation. We confirmed the requirements of the defined TFs and identified their action mechanisms.
